Here we go again. Automaker Fisker throws its hat into thewith its announcement of the official fuel economy and emissions ratings for its Karma plug-in hybrid electric vehicle.
According to Fisker, the Karma will have an economy rating of 3.5L/100km (which works out to 67.2 mpg) and emit just 83g CO2/km, according to Society of Automotive Engineers estimates. Wait, does that mean that the Karma--a sports car that outputs 403 horsepower and hits 62 mph in an estimated six-seconds--may be more fuel efficient than the 2010 Prius.
According to Fisker:
"Fueling the Karma could cost just 0.02 euro/km ($0.03/mile), consuming as little as 21 kilowatt hours per 100km in its electric-only Stealth mode, according to SAE methodology. However, a real-world annual average would be closer to 0.05 euro/km ($0.07/mile) based on a mix of Stealth and Sport (gasoline) mode use. Actual economy and emission results will vary depending on individual driving habits and usage requirements."
The key here lies in that last sentence about "individual driving habits." With 400-plus ponies on tap, how many drivers will be able to resist laying into the pedal on the right to get anywhere close to the claimed 67.2 mpg?
The Karma will be present at the Frankfurt auto show next week, as part of its German market debut.
